In Syria, the convoy with humanitarian aid was attacked

The convoy with humanitarian aid for 78 thousand people came under attack near the Syrian city of Aleppo on Monday, reported according to the United Nations.

Officials from the UN and the US said they were "outraged" by the incident in which, according to the UN destroyed 18 of the 31 trucks in the convoy. 12 people involved in helping have been killed, according to the Syrian Observatory for human rights, a U.K.-based organization that monitors the conflict in Syria.

Syrian cease-fire hanging on by a thread. No one has claimed responsibility for these attacks. It is not clear if the convoy was hit by an airstrike or a ground attack. The warehouse of the Syrian Arab Red Crescent also suffered, according to the UN. Humanitarian assistance and the warehouse were both in the al-Kubra, North-West of Aleppo. At least 32 people in total were killed in separate attacks in Aleppo and its Western suburbs.

The violence happened just a few hours after the Syrian authorities said that the fragile cease-fire in the war-torn country is over. Whole areas are cut off from humanitarian agencies - trucks, destined for the Eastern part of Aleppo, where an estimated 250 thousand civilians left without food, medicine and water.

"Our outrage over this attack is huge," said Staffan de Mistura, the UN special representative on Syria. "The convoy was the result of a lengthy resolution process and preparations for assisting isolated civilians."

The US state Department is not directly to blame for the attack, said in a statement that it was "a flagrant violation" of the cease-fire and make him reconsider whether he will continue to cooperate with Russia.
